FIELD OF THE INVENTION

The present invention relates to lighting devices. More particularly, the present invention relates to safety lighting devices for providing a warning or alert to persons within the vicinity of the lighting device.

BACKGROUND OF THE INVENTION

Traditionally, roadside safety flares have been used to provide a warning or alert to passing motorists of an accident or mishap. Police officers, highway patrol officers and safety officers all use roadside safety flares when they need to alert passing motorists to a potential hazard in the roadway. The presence of a flare alerts motorists to the existence of a hazard and of the need to slow down.

The conventional flare is an incendiary device which must be ignited. When the flare is ignited there is a risk of burning to the user. Also, when burning, the flare releases noxious fumes. The conventional flare is also a one-time use device with a short lifetime which must be discarded after use.

In other scenarios it is desirable to use a lighting device to illuminate a darkened area in order to aid in navigation and to indicate the presence of an individual or other object. Flashlights, strobe lights, and candles have often been used to shine light in a darkened area and to alert to the presence of an individual. However, in certain instances it is not practical to carry a portable light, such when as traversing a short space from a car to a front door, or when walking a darkened hallway in order to use the restroom or to get a drink of water. Further, a light source may not initially be needed but becomes necessary when it becomes dark. In such cases, it may be desirable to operate a light only intermittently or to control the light with an external source.

In some embodiments, there is also a connecting port 16 within a center cutout of two protective posts 12 disposed on opposite sides of the safety beacon 10.

A set of safety beacons coupled together by cables is illustrated in FIG. 5. The set of safety beacons illustrated in FIG. 5 includes four safety beacons for exemplary purposes. It should be understood that any number of safety beacons can be coupled together in this manner. A first safety beacon 50 is coupled to a second safety beacon 52 by a connecting cable 58. The second safety beacon 52 is coupled to a third safety beacon 54 by a connecting cable 60. The third safety beacon 54 is coupled to a fourth safety beacon 56 by a connecting cable 62. Each of the cables 58, 60 and 62 include a plug 64 on each end which fits into a connecting port 16 on the safety beacon. A power cable 66 is also plugged into the first safety beacon 50 for providing power to the set of safety beacons. The power cable 66 includes a plug 68 configured to plug into a conventional wall power outlet. The power cable 66 can also include a plug to plug into a vehicle power adapter, such as a cigarette lighter. The power cable 66 is also used to recharge the rechargeable battery within the safety beacon, as will be discussed below.

When coupled together by a cable, the safety beacons share power and control signals. When the power cable 66 is plugged into a power source and to a safety beacon within the set, all of the safety beacons coupled together within the set draw power from the power source. When none of the safety beacons within the set are coupled to a power cable 66, the safety beacons within the set each draw power first from their own rechargeable battery and then from the rechargeable batteries of the other safety beacons within the set, until none of the rechargeable batteries have any power remaining. Using the remote control 200 (FIG. 1), the safety beacons within the set can be controlled to all have a steady light or blink. The safety beacons within the set can also be controlled to each flash sequentially up and down the set of safety beacons, by passing an alternating control signal through the cables.

In an alternate embodiment, the safety beacon includes a wireless transceiver not only for receiving control signals from the remote control device, but also for wirelessly sending and receiving control signals to and from other safety beacons. In this alternate embodiment, the safety beacons wirelessly pass control signals in order to provide sequential flashing illumination up and down the set of safety beacons, without the need for connecting cables.

A set of safety beacons coupled together by cables and coupled to a vehicle for power is illustrated in FIG. 6. In the exemplary configuration of FIG. 6, a power cable 106 is coupled between a power adapter within a vehicle 112 and a first safety beacon 100. The first safety beacon 100 is coupled to a second safety beacon 102 by a connecting cable 108. The second safety beacon 102 is coupled to a third safety beacon 104 by a connecting cable 110. The power cable 106 includes a plug on one end which fits into the first safety beacon 100 and a plug on the other end which fits into the power adapter within the vehicle 112. Each of the connecting cables 108 and 110 include a plug on each end which fits into a connecting port on the safety beacon.

In the configuration illustrated in FIG. 6, the power cable 106 provides power from the vehicle 112 to each of the safety beacons 100, 102 and 104, through the connecting cables 108 and 110. The power cable 106 is also used to recharge the rechargeable battery within the safety beacons 100, 102 and 104. In this configuration, in a unison mode, the set of connected safety beacons can be controlled to flash in unison with the vehicle's hazard lights, brake lights or turn signal.

An alternate embodiment of the safety beacon of the present invention is illustrated in FIG. 7. Within the alternate embodiment of FIG. 7, the appearance of the safety beacon 120 is altered in order to appear like a bug, with the addition of the antennae 122 and the stickers 124. The bug-like safety beacon 120 is meant to appeal to children in order to encourage children to use the safety beacon when playing in the front of their house or in other locations near busy traffic. Use of the safety beacon of the present invention in these circumstances will alert motorists of the presence of children playing and encourage them to slow down. The outer housing of the safety beacon can have different colors and interchangeable lenses in order to change the appearance of the safety beacon for different uses and conditions.

The components within an embodiment of the safety beacon of the present invention are illustrated in FIG. 8A. To assemble the safety beacon, a printed circuit board 250, supporting the LEDs 260 and including a rechargeable battery 266, a controller circuit 264, a wireless receiver 262 and connectors 252 and 254, is positioned within the base 14, the port connectors 256 are coupled to the connectors 252, a power connector (not shown) is coupled to the connector 254 and then the outer housing 11 is screwed into the base 14. The outer housing 11 includes a threaded bottom 270 which is received by the base 14 in order to securely couple the outer housing 11 to the base 14.

On the printed circuit board 250, the controller circuit 264 is coupled to the rechargeable battery 266 by the connector 268. The controller circuit 264 is also coupled to control the operation of the LEDs 260. The controller circuit 264 is also coupled to the wireless receiver 262 for receiving wireless control signals from the remote control device 200 (FIG. 1). The controller circuit 264 is coupled to the connectors 252. In some embodiments, the LEDs 260 are positioned on a support 280 supported above the printed circuit 250 by the rigid supports 282.

When the printed circuit board 250 is installed within the base 14, the connectors 252 are coupled to the port connectors 256. The port connectors 256 are coupled to the ports 16 for providing the signals from the corresponding connecting cable to the controller circuit 264. When the printed circuit board 250 is installed within the base 14, the power connector 254 is coupled to a corresponding power connector coupled to the power switch 18. Once the printed circuit board 250 is installed and connected to the appropriate ports and power switch 18, the outer housing 11 is then screwed into the base 14 to complete the assembly of the safety beacon 10. Alternatively, as discussed above, the outer housing 11 is coupled to the base 14 in any appropriate manner, in order to complete the assembly of the safety beacon 10, including by snap fit. If the battery 266 or an LED 260 needs to be replaced, the outer housing 11 can be unscrewed or unsnapped in order to allow access to the printed circuit board 250, its components and the LEDs 260.

The components within an alternate embodiment of the present invention are illustrated in FIG. 8B. In the embodiment illustrated in FIG. 8B, the LEDs 260 are included on the printed circuit board 250.

In operation, a single safety beacon is used by itself or multiple safety beacons are coupled together by cables in order to operate as a group. The safety beacons are turned on by using either a remote control device, as described above, or pressing the power button. In some embodiments, once turned on, the safety beacons provides steady illumination. The safety beacons can also be controlled to provide blinking illumination or if connected in a set, to provide sequentially blinking illumination up and down the connected set of safety beacons. The safety beacons are coupled to a power source, such as a vehicle power adapter or a power outlet for drawing power for operation and for drawing power to recharge the rechargeable battery within the safety beacon. Alternatively, the battery source within the safety beacon is any appropriate battery source, including but not limited to a replaceable battery and a solar battery.

If multiple safety beacons are coupled together in a set, when first powered on, all of the safety beacons will start with a steady illumination. If the user then pushes the light patterns button on the remote control or toggles the power switch to the sequentially blinking mode, the first safety beacon will blink on and the other safety beacons will be turned off. The first safety beacon will then send a control signal to the next safety beacon through the connecting cable. When the next safety beacon receives this control signal, the next safety beacon will then turn on and then send a control signal to the next safety beacon within the set. When the final safety beacon within the set receives the control signal, it will turn on and then send the control signal back to the previous safety beacon. In this manner, the safety beacons provide a continuous sequential illumination with one safety beacon flashing at a time. In the alternate embodiment described above including wireless control communications between safety beacons, the safety beacons pass the control signals necessary for sequential illumination wirelessly between the safety beacons within the set.

The safety beacon of the present invention can be used in many different circumstances and situations. One of the main uses for the safety beacon of the present invention will be in the field of automotive safety. A power cable can be plugged into a vehicle power adapter, as described above, or hardwired into the vehicle's electrical system with a power and recharging port available for connection to a safety beacon by a cable. As an automotive safety beacon, the safety beacon can be positioned on the roadway behind the automobile, as shown in FIG. 6, or attached to the automobile using the magnetic bottom. This feature is extremely beneficial on roads with no shoulder or on city streets where there may be no room for conventional flares or lights to be placed on the ground near the automobile. Using the magnetic bottom, the safety beacon can also be attached to vehicles being towed. It should be apparent to those skilled in the art that any other appropriate means for affixing the safety beacon to a surface can be used, including but not limited to screws, nails, velcro and tape. Traffic control personnel can also use safety beacons to help direct traffic and alert motorists to traffic patterns. Safety beacons can be used at major events for traffic control and illuminating pathways to be followed by automobiles or other vehicles. Safety beacons can also be used for funeral processions as a notification to other drivers as to their need to stay grouped together.

Roadway workers and cleanup crews can also use safety beacons for protection to notify passing traffic that they are working near or on the roadside. A supporting base adapter which fits into a standard safety cone is illustrated in FIG. 9A. The supporting base adapter 300 of FIG. 9A fits inside a safety cone 302 and provides a platform on which a safety beacon is placed. The safety beacon is then placed on the platform of the base adapter 300 and can operate on top of the safety cone 302. A supporting base adapter which fits over a standard safety cone is illustrated in FIG. 9B. The supporting base adapter 310 of FIG. 9B includes a sleeve which fits over a safety cone 302 and provides a platform on which a safety beacon is placed. The safety beacon is then placed on the platform of the base adapter 310 and can operate on top of the safety cone 302. In an alternate embodiment, the safety beacon includes a GPS chip for determining its location and a transceiver for communicating the location of the safety beacon for tracking purposes.
